Two issues with communicating data over a wireless network are requesting acknowledgements for received data and acknowledging received data. Requesting acknowledgement of received data and acknowledging received data consumes bandwidth. Moreover, with the use of some protocols a large number of stations may be transmitting concurrently in both the spatial domain and time domain. Additionally, consumers often demand more and more bandwidth for their applications.
Thus there are general needs for systems, apparatus, and methods that reduce signaling, bandwidth and delay associated with communicating requests for acknowledgements and communicating acknowledgments.
